Raven Stole the Sun -
Short version, as told by Marilyn Whirlwind from the Northern Exposure TV show:
A long time ago, the raven looked down from the sky and saw that the people of the world were living in darkness. The ball of light was kept hidden by a selfish old chief. So the raven turned himself into a spruce needle and floated on the river where the chief's daughter came for water. She drank the spruce needle. She became pregnant and gave birth to a boy, who was the raven in disguise. The baby cried and cried until the chief gave him the ball of light to play with. As soon as he had the light, the raven turned back into himself. The raven carried the light into the sky. From then on, we no longer lived in darkness.
Longer version, from El's files, so not sure of the source:
There was a time many years ago when the earth was covered in darkness. An inky pitch blanketed the world making it very difficult for anyone to hunt or fish or gather berries for food. An old man lived along the banks of a stream with his daughter who may have been very beautiful or possibly quite homely. This didn't matter to the old man however because after all it was dark and who could tell.
The reason why the world was dark had to do with the old man who had a box that contained a box that held many other boxes. In the very last box was all the light in the universe and this was a treasure he selfishly kept to himself.
The mischievious Raven existed at that time because he always had. He was none too happy about the state of the world for he blundered about in the darkbumping into everything. His interfering nature peaked one day when he stumbled by the old man's hut and overheard him muttering about his boxes. He instantly decided to steal the light but first had to find a way to get inside the hut.
Each day the young girl would go to the stream to fetch water so the Raven transformed himself into a tiny hemlock needle and floated into the girl's bucket. Working a bit of his "trickster" magic, he made the girl thirsty and as she took a drink he slipped down her throat. Once down in her warm insides he changed again; this time into a small human being and took a very long nap.
The girl did not know what was happening to her and didn't tell her father. One day the Raven emerged as a little boy child. If anyone could have seen him in the dark, they would have noticed that he was a peculiar looking child with a long beaklike nose, a few feathers here and there, and the unmistakably shining eyes of the Raven.
Both father and daughter were delighted with their new addition and played with him for hours on end. As the child explored his new surroundings he soon determined that the light must be kept in the big box in the corner. When he first tried to open the box, his grandfather scolded him profusely, which in turn started a crying and squawking fit the likes of which the old man had never seen. As grandfathers have done since the beginning of time he caved in and gave the child the biggest box to play with. This brought peace to the hut for a brief time but it wasn't long until the child pulled his scam again, and again, and again until finally only one box remained.
After much coaxing and wailing the old man at last agreed to let the child play with the light for only a moment. As he tossed the ball of light the child transformed into the Raven and snatching the light in his beak, flew through the smoke hole and up into the sky.
The world was instantly changed forever. Mountains sprang into the bright sky and reflections danced on the rivers and oceans. Far away, the Eagle was awakened and launched skyward - his target now clearly in sight.
Raven was so caught up in all the excitement of the newly revealed world that he nearly didn't see the Eagle bearing down on him. Swerving sharply to escape the outstretched talons, he dropped nearly half of the ball of light, which fell to the earth. Shattering into one large and many small pieces on the rocky ground the bits of light bounced back up into the heavens where they remain to this day as the moon and the stars.
The Eagle pursued Raven beyond the rim of the world and exhausted by the long chase, Raven let go of what light still remained. Floating gracefully above the clouds, the sun as we now know it started up over the mountains to the east.
The first rays of the morning sun brought light through the smoke hole of the old man's house. He was weeping in sorrow over his great loss and looking up, saw his daughter for the first time. She was very beautiful and smiling, he began to feel a little better.
Different version, from Wikipedia:
Long ago, near the beginning of the world, Gray Eagle was the guardian of the Sun, Moon and Stars, of fresh water, and of fire. Gray Eagle hated people so much that he kept these things hidden. People lived in darkness, without fire and without fresh water.
Gray Eagle had a beautiful daughter, and Raven fell in love with her. At that time Raven was a handsome young man. He changed himself into a snow-white bird, and as a snow-white bird he pleased Gray Eagle's daughter. She invited him to her father's longhouse.
When Raven saw the Sun, Moon and stars, and fresh water hanging on the sides of Eagle's lodge, he knew what he should do. He watched for his chance to seize them when no one was looking. He stole all of them, and a brand of fire also, and flew out of the longhouse through the smoke hole. As soon as Raven got outside he hung the Sun up in the sky. It made so much light that he was able to fly far out to an island in the middle of the ocean. When the Sun set, he fastened the Moon up in the sky and hung the stars around in different places. By this new light he kept on flying, carrying with him the fresh water and the brand of fire he had stolen.
He flew back over the land. When he had reached the right place, he dropped all the water he had stolen. It fell to the ground and there became the source of all the fresh-water streams and lakes in the world. Then Raven flew on, holding the brand of fire in his bill. The smoke from the fire blew back over his white feathers and made them black. When his bill began to burn, he had to drop the firebrand. It struck rocks and hid itself within them. That is why, if you strike two stones together, sparks of fire will drop out.
Raven's feathers never became white again after they were blackened by the smoke from the firebrand. That is why Raven is now a black bird.
And here's a little shapeshifter treat for those of you who consider Raven to be your totem animal...it was sent to me by a friend so I'm not sure who the artist is - but I'd sure like to find out!
